If we start from one vertex, travel along a path and end up at the starting vertex, then this path is a cycle. Cycle detection is the process of detecting these cycles. Figure 5 shows an animation of traversing a cycle. Algorithms. Floyd cycle detection algorithm
WebJul 23, 2024 · Given a singly Linked List, detect if it contains a loop or not. Input: Output: True. Input: 1→ 2→ 3→ NULL. Output: False. Generally, the last node of the Linked List points to a NULL pointer, which indicates the end of the Linked List. But in Linked List containing a loop, the last node of the Linked List points to some internal node ...
